What is age adjusted death rate?

  • Different states or regions have different age structures.

  • Older populations naturally have higher death rates so comparing raw death rates across states would be misleading.

  • To make fair comparisons across the states, public health stats use age adjustment instead of uing raw numbers.

What is the death rate by cause and state?

How do the Amount of Deaths and Age Adjusted Death Rate Compare?

A Closer Look Into Heart Disease and Cancer

When we look at this data, we can notice that there has been a change in Heart Disease and Cancer throughout these years. When I searched it up a bit more, it says that there can be changes throughout the years due to better technology. Due to better technology, these diseases are faster to detect. Therefore the age gap between the amount of deaths is closing in. Creating a greater percentage for those who……..While deaths may be high, this can also be due to a higher population increasing through the time.
